Color in the tube as your total debt falls. Every mark is ten percent of the way there.

The debt thermometer is the oldest trick in personal finance and it still works: a tube with your total debt written in the bulb, and a marker to color it in every time you pay some off. It works because it is visible. A spreadsheet lives in a folder; a thermometer lives on the fridge, where you and everyone in the house walk past it a dozen times a day.

This version has ten marks up the side, one for every ten percent of the total, with a line beside each to write the dollar amount paid at that point. There is a small payment log on the right so you can note each payment before you color, and boxes for the start date and the debt-free goal.

It is meant to be filled in by hand, so the bulb is left white for your number and the tube is empty. Choose a color you like; you will be looking at it for a while. When the tube is full, keep the sheet. Very few people throw away a finished thermometer.

How to use it

  1. Add up every debt (the debt tracker is the page for that) and write the total in the bulb.
  2. Fill in the ten marks. Divide the total by ten. The 10% line is that number, 20% is twice it, and so on up to the total at the top.
  3. Log each payment in the table on the right and update the "paid so far" column.
  4. Color the tube up to the amount you have paid so far. Each time you cross a mark, stop and notice it.

Tips that make it stick

  • Put the total in the bulb even if it scares you. The thermometer only works if the whole distance is on the page.
  • Color from the bottom up in one color, and use a different color for any windfall payments so you can see where the jumps came from.
  • One thermometer for the whole pile, or one per debt for a snowball: a small debt fills fast and that first full tube is a real moment.

Common questions

Up, as you pay. The bottom of the tube is zero paid and the top is the full total, so the tube fills toward the goal. Filling something up feels like progress in a way that emptying it does not, which is the whole trick of the thermometer.

Use the total on the day you start and measure payments against it. Interest means you will pay a little more than the bulb says before the last balance hits zero; when that happens, color right to the top anyway and write the extra beside it. The thermometer is a motivation tool, not an accounting one.

Both work. One for the total gives the big picture. One per debt suits the snowball method, because the smallest debt's tube fills quickly and gives you an early finish to celebrate. Some people keep a big one for the total and a small stack for the individual debts.
